What is the difference between high temperature resistant paint and ordinary paint?
1.What is high temperature resistant coating?
High temperature resistant coatings, heat resistant coatings, as the name suggests, that can withstand high temperature oxidation and other moderately corrosive coatings.Silicone high temperature resistant coating: by the modified material silicone resin, heat resistant corrosion paste, preservatives, epoxy curing agent, organic solvents, etc.Silicone heat resistance is generally in the middle of 100℃-1200℃.The high temperature coating can obtain stable process performance in the natural environment, and is not easy to fall off, bubble, crack, break, etch and light fade.
Contrast ordinary paint with the widely used epoxy resin paint.Epoxy coating at the present stage in architectural coatings, architectural coatings with good adhesion force, applicable to steel parts of epoxy coating, architectural coating is very reliable, not easy to drop paint.Epoxy coating on steel, concrete, FRP anticorrosive, galvanized steel and other raw materials adhesive force, than the general glycolic acid nitro and other building coatings, but also better than many coatings.
So what is the difference between high temperature resistant coatings and epoxy coatings?
2.What is the difference between high temperature resistant paint and ordinary paint?
(1) strong adhesion: architectural coating is very firm, not easy to drop.The broken epoxy resin building coating has very good adhesion to metal materials such as steel, concrete, FRP anticorrosive, galvanized steel (modified epoxy coating), concrete, wood and other raw materials.
(2) epoxy resin resin resin fat building coating physical properties of high quality, wear resistance, impact resistance: epoxy resin adhesive building coating film perseverance, impact resistance, wear resistance, bending resistance.It is suitable for coating of mining machinery, engineering equipment, etc.It is not easy to crack due to temperature changes and other factors.
(3) excellent corrosion resistance, prepreg resistance: epoxy resin adhesive structure is stable, coating for acid resistance, alkali resistance, solvent resistance of epoxy coating dry solid structure of high density, corrosion chemicals are difficult to penetrate, strong prepreg resistance.
(4) the organic chemical characteristics of epoxy resin group is more active, can produce and process a variety of anticorrosive coatings.For example, can be made into solvent free coatings, high solid paint, electrostatic powder, water-based paint (anticorrosive material development prospects) and other energy-saving performance coatings.
(5) high storage stability, long shelf life.When curing agent is not added, epoxy resin adhesive building coating is not solid, and can be placed for about 2 years.
(6) the disadvantage of epoxy resin paint is bad weather resistance, easy aging.Sunlight irradiation for a long time may appear the phenomenon of powder, so can only be used for primer or indoor paint;Decoration is poor, luster is not easy to maintain.The engineering construction natural environment is high, the film solidification is slow, the actual effect is poor.Generally, it needs to be used in an environment greater than 5℃.
3.What are the characteristics of organosilicon high temperature resistant coating?
(1)heat resistance 200-1200℃.Within the range of high temperature resistance, the double silicone material high temperature coating is divided into many levels, spacing 100 levels, from 00 to 1200 temperature categories, in order to consider the provisions of different building coatings and high temperature resistance standards.
(2)resistant to heat and cold alternately.According to the heat - cold circulation system test to detect the high temperature resistant coating of high temperature film.When the temperature difference changes strongly, the layer sample is removed from the drying box, placed in cold water, and then placed in the drying box, the hot and cold circulation system reaches about 10 times, the hot and cold paint film is intact, and the coating does not fall off.
(3)the film color is diverse.The color of the film is diverse, good decorative, and the coating does not change color under high temperature.
(4)protect the substrate oxidation.High temperature resistant coating resistant to organic chemical atmosphere, acid, alkali, heat, moisture, to protect the substrate from erosion.
(5)high temperature does not fall off.High temperature resistant coatings and architectural coatings have excellent adhesion, not easy to cause cracks, bubbles and fall in strong temperature changes.
4.Summary
In contrast, high temperature resistant coatings and general epoxy resin adhesive building coatings have advantages and disadvantages, the main uses are also different, need to make a choice according to their own situation.These two are industrial paint, in addition to epoxy paint, also aerobic building paint, acrylic paint and other industrial paint, now there are a variety of oil soluble building paint and water-based paint, please choose according to their own good use.If you do not understand the characteristics of high temperature resistant paint and ordinary paint, can not buy, please contact us directly, we will provide more reasonable and optimized coating solutions according to your actual situation!
